Description

Technical Field

[0001] The invention relates to the technical field of injection molding machines, in particular to a cable-locking mold structure for a large-tonnage injection molding machine. Background Art

[0002] Plastic injection molding technology, a core process for polymer processing, is widely used in industries such as automotive, aerospace, and electronics. Large-tonnage injection molding machines must meet the molding demands of large, complex components. The performance of their clamping structure directly determines product precision, production efficiency, and equipment reliability. The core function of the clamping structure is to close and lock the mold through the clamping assembly and to facilitate demolding after injection. The connection method of key components such as the clamping section is a significant factor influencing the performance of the clamping structure.

[0003] The clamping structure of a large-tonnage injection molding machine is the core component that enables mold closure and injection molding. Its structural stability and ease of maintenance directly impact production efficiency and product quality. In the clamping structure of traditional large-tonnage injection molding machines, key components such as the clamping section are typically bolted or fixed assembly structures. When the clamping assembly needs to be repaired, replaced, or debugged, it is necessary to remove a large number of bolts and fasteners to separate the components. Summary of the Invention

[0004] In response to the deficiencies of the prior art, the present invention provides a cable-locking mold structure for a large-tonnage injection molding machine, which solves the problem that key components such as the clamping section in the prior art usually adopt bolt connections or fixed assembly structures, and the components need to be separated by removing a large number of bolts or fasteners.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a cable locking structure for a large-tonnage injection molding machine, comprising a transmission assembly, a fixed frame is provided on the outside of the transmission assembly, a plurality of connecting assemblies are provided on the inside of the fixed frame, a fixing nut is threadedly connected to the middle external portion of the connecting assembly, a plurality of extrusion rods are fixedly connected to the external portion of one side of the fixed frame, a clamping segment 1 is slidably connected to the external portion of one side of the connecting assembly, compensation assemblies are fixedly connected to the external portions of both sides of the clamping segment 1, the external portion of the extrusion rod passes through the interior of the clamping segment 1, a clamping segment 2 is provided on one side of the connecting assembly, mounting buckles are fixedly connected to the external portions of the clamping segment 2, and the connecting assembly and the clamping segment 2 are clamped together by a disassembly assembly.

[0006] By adopting the above technical solution, and utilizing the wedge-shaped connection between the clamping block and the fixing buckle in the disassembly assembly, the handle drives the rotating column to drive the release block to squeeze the fixing column three, overcoming the elastic force of spring two to disengage the clamping block, forming a mechanical quick-release mechanism, and achieving rapid disassembly of the clamping section two and the connecting assembly. Compared to traditional bolt connections, this invention can significantly shorten the time required for a single disassembly, while effectively avoiding assembly deviations caused by threaded hole wear, meeting the high-load operating conditions of large-tonnage injection molding machines. While ensuring connection strength, it significantly improves the maintainability and production efficiency of the equipment.

[0007] Preferably, the transmission assembly includes a hydraulic cylinder, the external part of the hydraulic cylinder is fixedly connected to the baffle of the injection molding machine, the output end of the hydraulic cylinder is connected to a connecting plate, one side of the connecting plate is externally fixedly connected to a connecting rod, one side of the connecting rod is externally fixedly connected to the outer wall of the clamping section, and the external part of the connecting rod is slidably connected to the inside of the fixed frame.

[0008] Preferably, the connecting assembly includes a connecting section, a threaded section is provided in the middle of the connecting section, one side of the connecting section is externally fixedly connected to a fixing plate 1, the outside of the fixing plate 1 is externally fixedly connected to a fixing column 1, and the outside of the fixing column 1 is externally fixedly connected to a fixing buckle.

[0009] Preferably, the disassembly component includes a shell, the outside of the shell is arranged on the outside of the clamping section 2, the inside of the shell is fixedly connected to a fixing plate 2, the inside of the fixing plate 2 is provided with a limiting groove, the inside of the fixing plate 2 is slidably connected to a clamping block, the clamping block is slidably connected to the inside of the limiting groove, one side of the clamping block is fixedly connected to a fixing column 3, the outside of the fixing column 3 is slidably connected to the inside of the shell, a spring 2 is arranged on the outside of the fixing column 3, one end of the spring 2 is arranged on the outside of the clamping block, and the other end of the spring 2 is arranged on the inside of the shell, and the other side of the clamping block is clamped between the fixing plate 1 and the fixing buckle.

[0010] Preferably, the housing is rotatably connected to a rotating column, one side of the rotating column is externally fixedly connected to a release block, and the other side of the rotating column is externally fixedly connected to a handle.

[0011] Preferably, the compensation component includes a second fixing column, a first spring is provided inside the second fixing column, and compensation blocks are provided at the top and bottom ends of the first spring.

[0012] Preferably, the extrusion rod passes through the clamping section and extends to the outside thereof.

[0013] Preferably, the fixing nut is threadedly connected to the threaded section of the connecting section.

[0014] Preferably, the disassembly assembly drives the release block through the handle to push the clamping block out of the clamping connection.

[0015] Preferably, the compensation block contacts the mounting buckle through the elastic action of spring 1.

[0016] Working Principle: First, a hydraulic cylinder is fixed to the injection molding machine's baffle. Its output end pushes a connecting plate to slide within the fixed frame. The connecting plate is fixedly connected to clamping segment 1, driving it along the extruder rod and connecting assembly. Second, when the transmission assembly pushes clamping segment 1 out via the connecting rod, the extruder rod provides auxiliary support. When the transmission assembly retracts clamping segment 1 via the connecting rod, the extruder rod pushes the plastic part out, completing the automatic unloading process. Furthermore, the connecting segment in the connecting assembly uses a threaded section to mate with a fixing nut for position adjustment and securement. Next, clamping segment 2 is quickly connected and disconnected from the connecting assembly via the disassembly assembly. The operating handle rotates the rotating column, causing the release block to push the locking block out of the engagement between fixing plate 1 and the retaining buckle, completing disassembly. Finally, the compensating assembly ensures a tight fit of the clamping structure through the elastic action of spring 1. When clamping segment 1 is pushed out, the mounting buckle squeezes the compensating block, causing spring 1 to contract and engage the other end of the mounting buckle, preventing loose fit due to thermal expansion and contraction.

[0017] The present invention provides a cable clamping structure for a large-tonnage injection molding machine. It has the following beneficial effects: 1. The present invention utilizes the wedge-shaped clamping structure of the clamping block and the fixing buckle in the disassembly component. The handle drives the rotating column to drive the release block to squeeze the fixed column three, overcoming the elastic force of the spring two to disengage the clamping block, forming a mechanical quick unlocking mechanism, and realizing the rapid disassembly of the clamping section two and the connecting component. Compared with the traditional bolt connection method, it greatly shortens the maintenance time and significantly improves the equipment maintenance efficiency and maintainability.

[0018] 2. The present invention uses a hydraulic cylinder in the transmission assembly to drive the connecting plate and the connecting rod to move the clamping section. In conjunction with the through-type support structure of the extrusion rod, the conical surface at the front end of the extrusion rod is used to automatically eject the plastic part when the clamping section is retracted, thereby realizing automatic unloading after the injection molding is completed, effectively solving the problem of low efficiency of traditional manual unloading, and significantly improving the degree of production automation and processing efficiency.

[0019] 3. The present invention adopts a line contact sealing design between the compensation blocks at both ends of the spring in the compensation component and the mounting buckle. When the components produce relative displacement due to thermal expansion and contraction, the spring is compressed to store energy to absorb the deformation error, effectively solving the problem of sealing failure caused by thermal deformation during high-temperature injection molding and ensuring the molding accuracy of the product.

[0020] 4. The present invention uses a spiral transmission pair composed of the threaded section of the connecting section and the fixing nut in the connecting assembly. By rotating the fixing nut, the protruding length of the connecting section in the fixed frame can be accurately adjusted. Combined with the rigid connection structure formed by the fixing plate and the fixing buckle, the clamping position can be adjusted steplessly and firmly fastened, effectively improving the assembly accuracy and load-bearing stability of the clamping structure, and meeting the mechanical performance requirements during large-tonnage injection molding.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see the attached Figure 1 -Attached Figure 3The embodiment of the present invention provides a cable locking structure for a large-tonnage injection molding machine, comprising a transmission component 1, a fixed frame 2 being provided on the outside of the transmission component 1, a plurality of connecting components 3 being provided on the inside of the fixed frame 2, a fixing nut 4 being threadedly connected to the middle external portion of the connecting component 3, a plurality of extrusion rods 5 being fixedly connected to the external portion of one side of the fixed frame 2, a clamping segment 1 6 being slidably connected to the external portion of one side of the connecting component 3, a compensation component 8 being fixedly connected to the external portion of both sides of the clamping segment 1 6, the external portion of the extrusion rod 5 passing through the internal portion of the clamping segment 1 6, a clamping segment 2 7 being provided on one side of the connecting component 3, a mounting buckle 9 being fixedly connected to the external portion of both sides of the clamping segment 2 7, and the connecting component 3 and the clamping segment 2 7 being clamped together by a disassembly component 10.

[0025] Specifically, the hydraulic cylinder 11 in the transmission assembly 1 is fixed to the injection molding machine baffle. Its output end pushes the connecting plate 12 to slide within the fixed frame 2, thereby driving the clamping segment 1 (6) to move along the extruder 5 and the connecting assembly 3. During this process, the extruder 5 not only provides auxiliary support for the movement of the clamping segment 1 (6), but also ejects the plastic part when the transmission assembly 1 retracts, achieving automatic unloading. The connecting segment 31 of the connecting assembly 3 engages with the fixing nut 4 via a threaded section to adjust the position and tighten, ensuring the stability of the clamping structure. The clamping segment 2 (7) is quickly disassembled by snapping it into the connecting assembly 3 via the disassembly assembly 10, significantly improving maintenance efficiency. The spring 1 (82) in the compensation assembly 8 uses elasticity to keep the compensation block 83 in close contact with the mounting buckle 9. When the clamping segment 1 (6) is ejected, the mounting buckle 9 squeezes the compensation block 83, causing the spring 1 (82) to contract and snap onto the other end of the mounting buckle 9, effectively compensating for loose fit caused by thermal expansion and contraction, ensuring the sealing and stability of the clamping structure during high-tonnage injection molding.

[0026] The ejection of plastic parts and the clamping action are integrated through the extruder rod 5 and the transmission component 1, thereby improving the degree of production automation. The thread adjustment mechanism of the connecting component 3 and the fixing nut 4 can accurately adjust the clamping force according to different tonnage requirements and enhance the adaptability of the structure. The combination of the disassembly component 10 and the compensation component 8 not only solves the problem of inconvenient maintenance of traditional large-tonnage injection molding machines, but also avoids the loss of precision caused by thermal deformation through the elastic compensation mechanism.

[0027] Please see the attached Figure 2 and attached Figure 3 The transmission assembly 1 includes a hydraulic cylinder 11, the hydraulic cylinder 11 is fixedly connected to the injection molding machine baffle on the outside, the output end of the hydraulic cylinder 11 is connected to a connecting plate 12, one side of the connecting plate 12 is fixedly connected to a connecting rod 13 on the outside, one side of the connecting rod 13 is fixedly connected to the outer wall of the clamping section 6 on the outside, and the outside of the connecting rod 13 is slidably connected to the inside of the fixed frame 2.

[0028] Specifically, the hydraulic cylinder 11 is fixed to the baffle of the injection molding machine to form a stable fulcrum, and its output end pushes the connecting plate 12 to slide back and forth inside the fixed frame 2. The fixed frame 2 is rigidly connected to the frame through a bolt group, providing a zero-sway guide constraint for the transmission process. The L-shaped structure of the connecting plate 12 forms a welded rigid connection with the connecting rod 13 on one side. When the hydraulic cylinder 11 outputs thrust, the power is synchronously transmitted to the connecting rod 13 through the connecting plate 12 to the clamping section 6, causing it to make axial translation along the guide surface of the extrusion rod 5 and the connecting component 3. The extrusion rod 5 is fixed to the fixed frame 2 with a through-type interference fit, and its optical axis section passes through the linear bearing hole of the clamping section 6, serving as a support guide rail when the clamping section 6 moves, and using the front end conical surface structure to eject the molded plastic parts during the retraction stage of the hydraulic cylinder 11.

[0029] A closed-loop control is formed by the servo control system of the hydraulic cylinder 11 and the linear sliding pair of the connecting plate 12 to ensure uniform application of the clamping force during large-tonnage injection molding. The dual-function design of the extruder 5 integrates the ejection mechanism and the transmission guide, reducing the number of mechanical components and improving the space utilization of the equipment. The rectangular steel pipe frame structure of the fixed frame 2 ensures that there is no energy loss in the transmission process. The combination of the hydraulic cylinder 11 and the linear guide replaces the traditional connecting rod mechanism, eliminating the problem of clamping force attenuation caused by mechanical clearance. The through-type ejection design of the extruder 5 avoids the configuration of an additional ejection cylinder and reduces the equipment failure rate.

[0030] Please see the attached Figure 3 and attached Figure 4 The connecting component 3 includes a connecting section 31, a threaded section is provided in the middle of the connecting section 31, a fixing plate 32 is fixedly connected to the outside of one side of the connecting section 31, a fixing column 33 is fixedly connected to the outside of the fixing plate 32, and a fixing buckle 34 is fixedly connected to the outside of the fixing column 33; the fixing nut 4 is threadedly connected to the threaded section of the connecting section 31.

[0031] Specifically, the middle threaded section of the connecting section 31 and the fixing nut 4 form a spiral transmission pair. When the fixing nut 4 is rotated, the protruding length of the connecting section 31 in the fixing frame 2 can be adjusted axially. The fixing plate 32 fixed at one end of the connecting section 31 serves as a transmission medium. The fixing column 33 outside the fixing plate 32 adopts an interference fit to install the fixing buckle 34, forming a mechanical interface that is clamped with the disassembly component 10. The hook-type structure of the fixing buckle 34 can withstand lateral shear forces up to.

[0032] The threaded section adopts trapezoidal thread with a tooth angle of 30° to meet the self-locking conditions, and the thread lead angle is less than the friction angle to ensure that there is no creep in the position after adjustment. The welding node between the fixing plate 32 and the connecting section 31 is tested by ultrasonic testing to ensure that the load is transmitted without attenuation. The fitting clearance between the fixing column 33 and the fixing buckle 34 is controlled at 0.02-0.05mm, which not only ensures the smooth connection of the disassembly component 10, but also avoids shaking under heavy load.

[0033] By replacing the fixed connection with an adjustable thread design, the rigid support structure of the fixing plate 1 32 eliminates the gap problem of the traditional pin connection. The standardized interface design of the fixing buckle 34 and the disassembly component 10 effectively reduces the replacement time of the clamping section 2 7 and greatly improves the mold change efficiency of the equipment.

[0034] Please see the attached Figure 5 and attached Figure 6 The disassembly component 10 includes a shell 101, the exterior of the shell 101 is arranged on the exterior of the clamping section 2 7, the interior of the shell 101 is fixedly connected to a fixing plate 2 102, the interior of the fixing plate 2 102 is provided with a limiting groove 103, the interior of the fixing plate 2 102 is slidably connected to a card block 104, the card block 104 is slidably connected to the interior of the limiting groove 103, one side of the card block 104 is fixedly connected to a fixing column 3 105, the exterior of the fixing column 3 105 is slidably connected to the interior of the shell 101, and the exterior of the fixing column 3 105 is provided with Spring 2 106, one end of spring 2 106 is arranged on the outside of the block 104, and the other end of spring 2 106 is arranged on the inside of the shell 101, and the other side of the block 104 is externally clamped between the fixing plate 1 32 and the fixing buckle 34; the inside of the shell 101 is rotatably connected to a rotating column 107, one side of the rotating column 107 is externally fixedly connected to a release block 108, and the other side of the rotating column 107 is externally fixedly connected to a handle 109; the disassembly component 10 drives the release block 108 through the handle 109 to push the block 104 out of the clamping connection.

[0035] Specifically, the shell 101 is installed on the outer wall of the clamping section 2 7 through a rubber ring, and the rectangular limit groove 103 of the internal fixing plate 2 102 provides a linear motion guide for the block 104. The T-shaped cross-section of the block 104 prevents lateral shaking when it slides in the limit groove 103. The front end hook structure forms a wedge-shaped connection with the fixing buckle 34. The fixing column 3 105 passes through the guide hole of the shell 101, and its end is rigidly connected to the block 104. The externally sleeved spring 2 106 ensures that the block 104 and the fixing buckle 34 remain tightly connected under normal circumstances.

[0036] When the operating handle 109 rotates clockwise, the coaxial rotating column 107 drives the release block 108 to rotate synchronously. The eccentric wheel structure of the release block 108 squeezes the fixed column three 105, overcoming the elastic force of the spring two 106 to push the clamping block 104 to slide inward, so that its hook end disengages from the clamping slot of the fixing buckle 34, thereby realizing the rapid disassembly of the clamping section two 7.

[0037] Please see the attached Figure 7 and attached Figure 8 The compensation component 8 includes a second fixing column 81, a spring 82 is provided inside the second fixing column 81, and compensation blocks 83 are provided at the top and bottom ends of the spring 82; the compensation block 83 contacts the mounting buckle 9 through the elastic action of the spring 82.

[0038] Specifically, the inner hole of the second fixing column 81 is equipped with the first spring 82 , and the compensation blocks 83 at both ends of the first spring 82 are made of glass fiber composite material, and the hemispherical end surfaces thereof form a line contact sealing structure with the U-shaped groove of the mounting buckle 9 .

[0039] When the temperature rises during operation of the injection molding machine, causing the components to expand and contract due to heat, the relative displacement of the clamping section 1 6 and the clamping section 2 7 causes the mounting buckle 9 to squeeze the compensation block 83, and the spring 1 82 is further compressed to store energy, absorbing the thermal deformation through elastic deformation, thereby reducing the temperature deformation error of the clamping surface and reducing the flash defect rate of the product.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
